In my personal opinio starrk is the coolest and strongest espada and he will not die at least until he get to see shunsui¨s bankai and I think it must be hell of bankai ¨cause his shikai is damn cool so his bankai must be even coolest!!
The Carefree Combatant vs. The Lone Wolf: Captain Shunsui Kyōraku vs Coyote Starrk for me is going to be a good fight
hope some satrrk and shunsui survive or at least give hell of a battle!!!
